why is my code giving 'int' object is not subscriptable error?

Question

t= int(input())
ar=[]
chk=0
x=0
y=0
while(t>0)
    i=int(input())
    for l in range(i):
        ar= int(input())
    for l in range(i-1):
        for m in range(l+1,i):
            x=ar[l]
            y=ar[m]
            k=x*y
            if k in ar:
                continue
            else:
                chk=chk+1
    print(True)
    if chk>0:
        print(False)
    t-=1

Error:

x=ar[l]

TypeError: 'int' object is not subscriptable

in this program i am tryng to print true if all the all the pairs in the array follow the relation x= a*b where x is any element in array and a abd b are the elements of the pair.

ar is an integer: ar = int(input()). You can't subscript an integer. — kindall

In the loop above, put ar[l] = int(input()) instead of ar= int(input()) — Mad Physicist

What you intend to do is append the input to the ar. Use

ar.append(int(input())

instead of

ar = int(input())

which changes ar type from list to int, and it's no longer possible to access it using indices.

You are using ar wrong. First you use ar like a list, and then like an int.

ar=[]               # You are using ar like a list
ar= int(input())    # Now, you are using ar like an int

You have to append the value:

ar.append(int(input()))

Now you are making a good list!
